1, equipped with deodorization device. When building organic fertilizer equipment in the plant, deodorization devices of appropriate scale should be set up. The odorous gas produced by biological digestion and fermentation is fed to the biological digestion chamber through the negative pressure collection system installed on the top of the biological reaction chamber, sterilized and purified by the deodorization reflux device. This not only solves the impact of the odor on the whole warehouse air, but also plays a secondary utilization, which is conducive to aerobic and anaerobic reactions. The discharge room is equipped with a bioaerosol disinfection machine to keep the indoor air fresh.
2, biological deodorization through biochemical reaction decomposition and transformation of odor components, to achieve the purpose of deodorization. Most current applications use microbes to deal with odors. Therefore, it is also called microbial deodorization.
3, adsorption deodorization. Absorption is the principle by which one or more soluble components of a mixture of gases are dissolved in a liquid. Lotion water is a commonly used deodorant solvent, which is combined with Mn04, NaOCl, Ca(OH)2 or NaOH and other chemical oxidants, and can absorb and remove H2S, NH and other organic matter with water vapor. As mercaptan.
4. Biological filtration method. Bioactive fillers are filled into the treatment tank. The fillers are mainly peat, wood chips, branches, decomposed compost, soil, etc. The process of biological filter method is: after pressuring and prewetting, the odor from the bottom, and attached to the biofilm on the filler contact, adsorption by the membrane, can be degraded into water and carbon dioxide. Drain from top of filter.
